Hybrid tomato variety H1648

ABSTRACT

Hybrid tomato variety ‘H1648’ is described. The tomato variety is a ground-culture hybrid tomato variety suitable for machine harvest, and is adaptable to the climactic conditions of regions such as California (USA), Ontario (Canada), Australia, Portugal, Spain, and Italy.

FIELD

This disclosure relates to the field of plant breeding. In particular, this disclosure relates to a new tomato (Solanum lycopersicum) variety denominated ‘H1648’.

BACKGROUND

Breeding improved tomato varieties involves providing genetics that give an advantage to the grower, processor, consumer, or other members of the supply chain. The improvement may be in the form of field performance, disease resistance, factory performance, or a fruit quality characteristic. For a tomato variety to be suitable to be grown for processing, the variety must have a concentrated fruit setting and maturity, firm fruit, and sufficient rot tolerance to allow early fruit to remain rot-free while later fruit continues to develop and ripen.

Most commercial processing tomato varieties are hybrids resulting from a cross pollination of two true-breeding, inbred parents. Through the use of true-breeding lines, a hybrid is produced that often displays characteristics of each parent, and often demonstrates characteristics that are superior to either parent alone, or that allow a hybrid to mask inadequacies of the individual parents.

SUMMARY

Provided herein is a new and distinct tomato variety named ‘H1648’ that was developed to provide a ground-culture hybrid tomato variety that is suitable for machine harvest, and is adaptable to the climactic conditions of regions such as California (USA), Ontario (Canada), Australia, Portugal, Spain, and Italy.

DETAILED DESCRIPTION

Described herein is a new and distinct tomato variety named ‘H1648’ that was developed to provide a ground-culture hybrid tomato variety (i.e., not grown on stakes) that is suitable for machine harvest, and is adaptable to the climactic conditions of regions such as California (USA), Ontario (Canada), Australia, Portugal, Spain, and Italy.

Processing tomato quality parameters differ from those of fruit used in the fresh market. The processing characteristics are typically determined using a sample of hot-break tomato pulp or juice produced in a consistent manner to those familiar with the art. For example, a fixed mass of tomatoes may be cooked in a microwave oven for several minutes to halt any enzymatic breakdown of the sample, lost water is replaced, and the sample is pulped to remove skins and seed to produce a uniform juice sample. The juice sample can be analyzed for various quality parameters important to processing tomato including but not limited to gross viscosity measures such as juice Bostwick, soluble solids measures using a refractometer (ºBrix), measures of acidity and pH, and measures of color (e.g. Hunter a/b score and levels of lycopene). The value of these traits depends on the product that is being commercially produced by the processing factory. In some instances, a factory will put a higher value on a thick viscosity variety, whereas in other instances, a thin viscosity will make a superior product and is preferred.

Processing tomato varieties combining resistance to verticillium wilt race 1 (Verticillium dahlia), fusarium wilt race 1 and 2 (Fusarium oxysporum pv. lycopersici), and root knot nematode (Meloidogyne incognita) are highly desirable in most climates around the world. Varieties with tolerance to ripe fruit rots (extended field storage) are also desirable because they are conducive to once-over machine harvesting, particularly in regions where rain can occur during harvest or there are delays in a harvesting schedule.

Moreover, in regions such as California, the industry has seen a considerable increase in pressure from two particular diseases: tomato spotted wilt virus (TSWV) and Fusarium oxysporum pv. lycopersici race 3 (fusarium wilt race 3). Thus, varieties with resistance to either or both are in high demand by both growers and processors to ensure a productive crop cycle.

Processing tomato varieties that can produce high yields under intense pressure from bacterial diseases such as bacterial canker (Clavibacter michiganensis subsp. michiganensis) and bacterial spot, caused by various Xanthomonas species, are highly desirable in humid tomato production regions around the world, such as Ohio, Michigan, and Brazil.

Moreover, an additional important contribution that tomatoes provide to the human diet is the antioxidant lycopene. Specifically, processed tomato products are the primary source of tomato intake in the US diet and other countries around the world. Higher levels of lycopene are beneficial both from a nutritional standpoint and from a consumer perception and quality standpoint. Tomato varieties having higher levels of lycopene result in products with a deeper red color that can be considered an indicator of higher product quality. Thus, a tomato variety with a higher level of lycopene and improved color in general can be valuable from a nutritional standpoint, a quality standpoint, and desirability by the consumer. However, to be commercially viable, the tomato variety must perform acceptably in the field and factory as required by any other processing tomato variety. Often, varieties with enhanced lycopene suffer agronomic defects in yield, fruit firmness, or field storage.

Hybrid Tomato Variety ‘H1648’

Described herein is a new and distinct tomato variety named ‘H1648’ that was developed to provide a ground-culture hybrid tomato variety (i.e., not grown on stakes) that is suitable for machine or hand harvest, and is adaptable to humid climactic conditions of regions such as Michigan, Ohio, Indiana, Pennsylvania and southern Ontario Canada.

Plants of the tomato variety ‘H1648’ are resistant to verticillium wilt race 1, fusarium wilt races 1 and 2, root knot nematode, bacterial speck, bacterial spot and bacterial canker. Additionally, plants of the tomato variety ‘H1648’ have a vigorous upright vine compared to other tomato varieties of the same market class and very high yield potential. Fruit from the tomato variety ‘H1648’ is medium sized and has improved color compared to other tomato varieties of the same market class. Moreover, the tomato variety ‘H1648’ is adapted to culture in both humid growing regions such as the eastern United States, southern Ontario Canada and humid European regions.

Stability of the Variety ‘H1648’

Variety ‘H1648’ is uniform and stable within commercially acceptable limits. As is true with other tomato varieties, a small percentage of variants can occur within commercially acceptable limits for almost any characteristic during the course of repeated multiplication. However, no variants were observed during the two years in which the variety was observed to be uniform and stable.

Hybrid tomato variety ‘H1648’ has the following physiological, morphological, and other characteristics as set forth in Tables 1-4 below.

Comparison of ‘H1648’ to Closest Varieties

Data in Table 1, 3, and 4 are based primarily upon trials conducted in Collegeville, Calif. (USA) from two replications, non-staked, in a research plot environment. Comparisons among varieties for processing traits (Table 2) were done over two years of side-by side testing throughout California. Disease resistance and adaptability assessments are based upon numerous observations collected throughout California and in regions/climates with specific disease pressure for ripe fruit rots, bacterial spot, bacterial canker, early blight, and late blight, including Ontario (Canada).

H1648 can be distinguished from H3402 and H9553 in that it has a more vigorous vine with darker foliage, old gold crimson flower color, and larger fruit with improved internal color. H1648 represents a significant soluble solids (° Brix) advantage compared to industry standard varieties H3402 and H9553. Disease resistance in H1648 is superior to H3402, providing higher levels of resistance to bacterial canker and bacterial spot. In addition, H1648 is resistant to bacterial speck compared with susceptible variety H9553.

Further Embodiments

Additional methods include, without limitation, chasing selfs. Chasing selfs involves identifying inbred plants among tomato plants that have been grown from hybrid tomato seed. Once the seed is planted, the inbred plants may be identified and selected due to their decreased vigor relative to the hybrid plants that grow from the hybrid seed. By locating the inbred plants, isolating them from the rest of the plants, and self-pollinating them (i.e., “chasing selfs”), a breeder can obtain an inbred line that is identical to an inbred parent used to produce the hybrid. Accordingly, another aspect of the disclosure relates a method for producing an inbred tomato variety by: planting seed of the tomato variety ‘H1648’; growing plants from the seed; identifying one or more inbred tomato plants; controlling pollination in a manner which preserves homozygosity of the one or more inbred plants; and harvesting resultant seed from the one or more inbred plants. The step of identifying the one or more inbred tomato plants may further include identifying plants with decreased vigor, i.e., plants that appear less robust than plants of the tomato variety ‘H1648’. Tomato plants capable of expressing substantially all of the physiological and morphological characteristics of the parental inbred lines of tomato variety ‘H1648’ include tomato plants obtained by chasing selfs from seed of tomato variety ‘H1648’.

One of ordinary skill in the art will recognize that once a breeder has obtained inbred tomato plants by chasing selfs from seed of tomato variety ‘H1648’, the breeder can then produce new inbred plants such as by sib-pollinating, or by crossing one of the identified inbred tomato plant with a plant of the tomato variety ‘H1648’.

The disclosure further includes introducing one or more desired traits into the tomato variety ‘H1648’. For example, the desired trait may include male sterility, male fertility, herbicide resistance, insect resistance, disease resistance, and drought resistance.

The desired trait may be found on a single gene or combination of genes. The desired trait may be a genetic locus that is a dominant or recessive allele. The genetic locus may be a naturally occurring tomato gene introduced into the genome of a parent of the variety by backcrossing, a natural or induced mutation, or a transgene introduced through genetic transformation techniques. For a genetic locus introduced through transformation, the genetic locus may comprise one or more transgenes integrated at a single chromosomal location. Accordingly, the disclosure provides tomato plants or parts thereof that have been transformed with one or more transgenes (i.e., a genetic locus comprising a sequence introduced into the genome of a tomato plant by transformation) to provide a desired trait. In one aspect, the one or more transgenes are operably linked to at least one regulatory element.

The gene(s) may be introduced to tomato variety ‘H1648’ through a variety of well-known techniques, including for example, molecular biological, other genetic engineering, or plant breeding techniques, such as recurrent selection, backcrossing, pedigree breeding, molecular marker (Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), and Simple Sequence Repeats (SSRs) (also referred to as Microsatellites)), enhanced selection, genetic marker enhanced selection, and transformation. Accordingly, tomato seed, plants, and parts thereof produced by such genetic engineering or plant breed techniques are also part of the present disclosure.

Also provided herein are single locus converted plants and seeds developed by backcrossing wherein essentially all of the morphological and physiological characteristics of an inbred are recovered in addition to the characteristics conferred by the single locus transferred into the inbred via the backcrossing technique. A single locus may comprise one gene, or in the case of transgenic plants, one or more transgenes integrated into the host genome at a single site (locus). One or more locus conversion traits may be introduced into a single tomato variety.
